function - Haskell - lambda expression -

i trying understand what's useful , how use lambda expression in haskell. don't understand advantage of using lambda expression on convention way of defining functions. example, following: let add x y = x+y and can call add 5 6 and result of 11 know can following: let add = \x->(\y-> x+y) and same result. mentioned before, don't understand purpose of using lambda expression. also, typed following code (a nameless function?) prelude , gave me error message. let \x -> (\y->x+y) parse error (possibly incorrect indentation or mismatched backets) thank in advance! many haskell functions "higher-order functions", i.e., expect other functions parameters. often, functions want pass such higher-order function used once in program, @ particular point. it's more convenient use lambda expression define new local function purpose. here's example filters numbers greater ten given list: ghci> filter (\ x -> x &&...

(dot), discovered when testing folder name ending in "etc." it seems trailing dots totally removed before $_get has been populated. if put character after dot, it's fine, if uri ends in number of dots, removed is there way stop happening? you don't need exclude "?" , "#" in rewriterule since operates on uri (path), without query-string or anchor. so, enough: rewriterule ^shop/(.+) index.php?area=shop&folder=$1 [nc,qsa,l] that being said, not change fact dots stripped. this may result of multiviews being on. option makes apache try , resolve uris disregarding extensions. ...

oop - Function overloading with the only change in "uint32_t" & uint64_t" in pure virtual function in c++ -

-
i've pair pure virtual function defined inside c++ class, i've overloaded. code snippet below:: virtual uint64_t abc::getvalue()=0; virtual uint32_t abc::getvalue()=0; here, difference in function signature return type of getval() " uint32_t " & " uint64_t ".. it's throwing compilation error can't overloaded. plz me on this. you can't overload based on return type, on parameter types. because overload chosen based on how function called, , function call doesn't specify expected return type. options include: give functions different names; "return" value via reference parameter, rather return value; add dummy parameter, different type each version, specify return type; return "proxy" object that's convertible either type (although means you'll have single function, derived classes can't override 2 versions separately).

i've been reading volatile ( https://www.ibm.com/developerworks/java/library/j-jtp06197/ ) , came across bit says volatile write more expensive nonvolatile write. i can understand there increased cost associated volatile write given volatile way of synchronization want know how how volatile write more expensive nonvolatile write; perhaps have visibility across different thread stacks @ time @ volatile write made? here's why, according article have indicated: volatile writes considerably more expensive nonvolatile writes because of memory fencing required guarantee visibility still cheaper lock acquisition. [...] volatile reads cheap -- cheap nonvolatile reads and is, of course, true: memory fence operations bound writing , reads execute same way regardless of whether underlying variable volatile or not. however, volatile in java more volatile vs. nonvolatile memory read. in fact, in essence has nothing distinction: difference in concurrent seman...
